I have been actively using it for the last 10 months. I have three kids, 4-years-old and younger who all co-sleep with me, so as you can imagine, there has been many, many accidents made on my bed. This mattress protector saved my mattress from heavy and regular pee stains, vomit, drinks, food, marker and pen stains, etc. I highly recommend buying this product, especially if you have little ones. I'm a mom of four children, so I understand the need for such a product. This is what my mattress looks like through all of the accidents and stains! It's an absolutely amazing product, so don't hesitate to buy it for your mattress protection needs!
